The FCS-RDM is a remote display device specifically designed to communicate with the FCS Flexible Control System. It displays much of the same information as the FCS and can be viewed from a remote, relevant location such as a refrigeration application where there are two different entrances to the chiller room. The FCS-RDM employs connection loss detection to ensure the information that is displayed is current. Simple configurations including setting the Modbus ID and baud rate can be done in the field. The display can be configured to show / not show one or more channels of interest.
